+#. Load the current package definition from the repository database.
+#. Replace its version with the requested rollback target.
+#. Search the archive directory for built artifacts (packages and signatures) matching the target version.
+#. Add the found artifacts to the repository via the same path as ``package-add`` with ``PackageSource.Archive``.

+HTTP client
+^^^^^^^^^^^
+
+The ``ahriman.core.http`` package provides a HTTP client built on top of the ``requests`` library.
+
+The base class ``ahriman.core.http.SyncHttpClient`` wraps ``requests.Session`` and provides common features for all HTTP interactions: configurable timeouts, retry policies with exponential backoff (using ``urllib3.util.retry.Retry``), basic authentication, custom User-Agent header, error processing, and ``make_request`` method. The session is lazily created (via ``cached_property``).
+
+On top of that, ``ahriman.core.http.SyncAhrimanClient`` extends the base client for communication with the ahriman web service specifically. It adds automatic login on session creation (using configured credentials), ``X-Request-ID`` header injection and Unix socket transport support (via ``requests-unixsocket2``) if required.
